WTB: Langevin AT 601 - Pair

[Phrazemaster]

Hey all, doing a build of a pair of 176s and would like to add a T pad to the outputs. I know I could use a modern t attenuator but I’d like to use OEM parts.

Anyone have a pair of langevin AT 601s laying around? PM or email me.

Also I could use a Daven T-257-G or T-520-G

Thx

Mike
